Roger - Gryffindor Roger is typicl gryffindor. He can by little arrogant, bit brazen. He is talented and smart, but he hate study. (It is just so boring. :D) Roger always wants have good time, go out with friends, have fun, make some jokes. He is not worry about breaking rules during this times.(something like Marauders) In his heart is always place for true friends. And he defends them when they can not.
John - Slytherin I thing that John fits the most in Slytherin. It isn't because i think he is bad. John is really hard working. He has the best grade, and he is the best player on bass. He is very good in things what he does and he always pursues his goals. He seems withdrawn for people who don't know him. But he can by pretty wild in group of people, what he knows.(friends and family) He is very loyal to his family.
Brian - Hufflepuff Yeah everybody say that Brian is typical ravenclaw. I don't agree. Yes, he is the clever one but that doesn't mean he have to be in ravenclaw. "Several outstanding brains have emerged from Hufflepuff house over the centuries; these fine minds simply happened to be allied to outstanding qualities of patience, a strong work ethic and constancy, all traditional hallmarks of Hufflepuff House." from pottermore Brian is very loving person. He tries to help anybody. (even animal). He have good moral code and he is trying see only good in people. Meaby he can be little stubborn but he doesn't mean it badly. Of course he can get angry to. But it's not too often. He tries defend, what he cares about.
Freddie - Ravenclaw In ravenclaw don't have to be always just the smartest people. It is more about some kind of talent. Ravenclaws are the most distinctive and eccentric people. And that Freddie exactly is. He is genius in his field (legend). He is very distinctive and eccentric. He wears what he wants, he says what he wants, and he does what he wants. And this is exacly the thing which include in ravenclaw.
